What is the difference between these two function calls in PAL?

I'm using code tutorials & the documentation in order to get an idea of how to use PAL but I've noticed an inconsistency in either my interpretation or the examples online + the documentation.

I cannot find an example of the "PAL_LOGISTIC_REGRESSION" SQL function call in the documentation, only in code examples online. I'm attemping to do logistic regression on my own dataset rather than some sample data I can insert into a table and I've noticed that things are mysteriously missing from explanation.

This function call and these question marks are from the SAPHANAAcademy github. What are the arguments these question marks refer to? What is this function? These questions come from a comparison of this function call snippet and what is found in the following documentation:
